📖 Static demo — read-only snapshot
You’re browsing a static build of the Body IQ knowledge graph, so everything loads with no backend. A few things that need the live server are turned off here:
- Global search (sidebar) is disabled — it queries the API.
- The JSON API and the API “Try it” playgroundaren’t included.
- The data is a snapshot — it refreshes only when the demo is rebuilt, not live from the database.
Everything else — the body map, progression ladders, coverage heatmap, exercise finder, and all anatomy/exercise/source pages — works fully. The full app (live search + API + database) runs from the source on GitHub.
Cervical Retraction
Cervical Intervertebral Joints (C2-C7) • Cervical Spine • sagittal plane
Posterior translation of the head on the neck (chin tuck). Combines upper cervical flexion with lower cervical extension. In research literature, trained as craniocervical flexion (CCF) — see notes for clinical context.
Axis: medial-lateral
Clinical context: peer-reviewed literature does not study cervical retraction as an isolated movement. The evidence-based analog is craniocervical flexion (CCF) — upper cervical flexion with a subtle posterior head translation — which preferentially activates longus colli and longus capitis with minimal SCM activation. The exercises below are CCF-based interventions, which is what clinicians typically mean when they prescribe "retraction" or "chin tuck." Evidence: Falla 2012 (PMID 22156825), Blomgren 2018 (PMID 30486819), Cagnie 2008 (PMID 17991788).
Normal Range of Motion
Measured as linear translation of the tragus posteriorly, not goniometric degrees.
